Motion control method and device of flexible antenna transmission seat and antenna feed system

The invention discloses a motion control method and device of a flexible antenna transmission seat and an antenna servo system, and relates to the technical field of antenna transmission seat motion control, and the method comprises the following steps: employing a step-by-step control configuration of an open-loop control stage and a closed-loop control stage to achieve the rapid motion and precise pointing of an antenna; planning the movement speed and the movement time of the antenna transmission seat in the open-loop control stage by using the S-shaped speed curve; and an anti-saturation integral PI control algorithm is utilized to eliminate deviation in a closed-loop control stage, and accurate pointing is realized. According to the method, the methods of open-loop speed curve planning and tail end position closed-loop control are comprehensively adopted, the jerk of the flexible antenna in the movement process is in a constant value, the acceleration is in a primary curve change, and the speed is in a q
